Excellent now you have to do it a couple thousand times in parallel
sessions.

Great, to Apple fixed it.
Do you need code for testing the sysctl() stuff?
I was thinking of:
--------
if (limit > 0) {
#ifdef MACOSX
#define MAX_FILES_PER_PROC "kern.maxfilesperproc"
long current_limit;
size_t len = sizeof(current_limit);
if (sysctlbyname(MAX_FILES_PER_PROC, ¤t_limit, &len,
(void *) 0, (size_t) 0) < 0)
return (-1);
if (limit > current_limit)
limit = current_limit;
#else
if (limit > rl.rlim_max)
rl.rlim_cur = rl.rlim_max;
#endif
else
rl.rlim_cur = limit;
if (setrlimit(RLIMIT_NOFILE, &rl) < 0)
return (-1);
}
return (rl.rlim_cur);
--------
Or something close to that. I did not test the code.
